Unfriend people who do not post to Facebook or engage with anyone else. You'll find your posts start getting reach they never did before. Why? Facebook only releases your posts to a few people at first and watches what they do with it.

Turn on all security features like two-factor authentication. People who do that generally don't get hacked. Don't care? You will when you get hacked. Do the same for your email and other social services, too.

Make sure you like, comment and share other people's items. That teaches Facebook what kinds of things you like to see in your feed.
